FIELD OF THE INVENTION

The present invention generally relates to systems and methods that control or switch power to a variety of electrical devices. Specifically, the present invention in many preferred embodiments has application to home/commercial network integration automation systems in which electrical power to appliances and other electrical loads is controlled via commands received from a local or remote computer network.

In many preferred embodiments the present invention allows electrical loads to be controlled locally or remotely via an Internet-capable device (e.g., a smartphone, a tablet, or laptop) and provides a non-intrusive, secure, and blended load control interface that is compatible with home and commercial computer networks.

Within this context the present invention permits integration of computer networks to allow functionality in a coordinated/concerted fashion in network configurations that are local to and/or spanning network gateway routers.

PRIOR ART AND BACKGROUND OF THE INVENTION Background

There is a high demand in home automation/home energy control market for an easy to use home automation device—a wirelessly and remotely controlled AC power switch that can turn on and off AC power supply to consumer electronic devices and measure the energy consumption of the consumer electric loads. This demand is obvious in numerous consumer forums and is widely discussed in the prior art.

Such a home automation device can be configured to automatically turn on and off a consumer device at a chosen time and on certain conditions. In addition, the device measures the energy consumption and uses that information for energy usage planning and “smart” switching of the electronic device. This improves the quality of life as well as reducing energy consumption.

A home automation device that can remotely switch on and off AC power switch is not new. The prior art teaches power line based AC switches by which the control command is send over the power line and wireless AC switches where the control command is sent over a wireless link. These home automation devices can be categorized into two groups:

    • Non-Internet based home automation devices. A remote controller is required to send the control command to the devices over a communication protocol not compatible with Internet. Consumers cannot control them from anywhere. Examples are ZIGBEE® and Z-WAVE® based devices.
    • Internet based home automation devices. These devices can be accessed with Internet capable equipment, such as a smartphone or a laptop. Existing Internet based home automation devices, however, suffer the following drawbacks:
      • Consumers cannot easily access the devices both at home and away from home.
      • Consumers have to log on to a service provider's website while away from home, and from there read the data and control the automation device. Consumers cannot communicate with the device directly. This presents some security issues as well as performance issues.
      • This type of devices is usually intrusive to existing home network as consumers either need to get a new home gateway to work with the automation device, or add a new router or hub to the home network to “relay” the signals.

Home Automation Networking

Most homes today have the last mile communication connection (e.g., a cable link, a fiber optic or a telephone line). Inside a home there is a gateway device that terminates the last mile network and routes the signal between the consumer devices at home and the network outside home. The communication of the gateway with the home devices can be wireline or wireless. Wireline communication includes power line, cable, and Ethernet. But predominantly, the communication trend is wireless based on WiFi. The communication of the home gateway with home devices forms home network. In this document, it will be assumed that the home gateway is a WiFi AP and that the home network is a WiFi home network.

Existing home energy management system or a home automation system is a system that has a two-way communication with a service provider (e.g., a utility company or a security company) that monitors the home power consumption and exerts control such as switching on and off a device.

The challenges these systems encounter in their home deployment are:

    • Service Provider Centric vs. Consumer Centric—The service providers have the control, with consumers permission, over when and what data to collect and when and what device to control. This is a service provider centric approach. There are privacy issues and the issues of consumer's ability to access the data. For example, when a consumer is at home, must he/she login to a service provider's site to look at data and exercise control or can he/she easily access the information and exercise control directly from/to the automation devices at the home, from a laptop or a smartphone. Today's deployed automation and energy management system requires the consumer to remotely login to a service provider site for information and provides no method for easy and direct access to or control over the device.
    • Network Issues—When an automation device is deployed at home, it either has to work with existing home residential gateway (the AP) or replace the existing home gateway with a new home gateway that knows how to communicate with the automation device. With ZIGBEE® as part of the many automation/energy management system, it is frequently the case that a new home gateway must be used in place of the existing one. This “intrusive” setup that often requires professional setup forces consumers to make changes in their home network setup. In addition, once the energy management network is deployed at a home, it is not easy to deploy additional energy management devices from other vendors.
    • Performance—As mentioned above, many existing home energy systems do not allow consumers to access or control them DIRECTLY via a smartphone or a tablet, even if they are proximal to the energy system. Instead the consumer must either have to use a dedicated device like a remote control or have to go to a service provider's website to exercise control. It involves sending signals to the home gateway, to an Internet server, and back to the home gateway and back to the consumer's automation device. As a result, it introduces delays (sometimes significant delays) depending on the overall network traffic.

Deficiencies in the Prior Art

The prior art as detailed above suffers from the following deficiencies:

    • Prior art network integration systems generally do not permit integration of disparate types of home automation networks.
    • Prior art network integration systems generally do not interface well with the Internet and rely on proprietary interface protocols operating within a locally defined network interface to affect network integration functions.
    • Prior art network integration systems generally do not permit “nesting” or “subnetting” of control networks to define hierarchical control domains that can be accessed remotely via the Internet or some other network interface.
    • Prior art network integration systems do not allow coordinated/concerted network functionality in networks that are local to and/or span network gateway routers.
    • Prior art network integration systems do not permit interaction within a home automation network to permit creation of “social networks” within the home automation framework.
    • Prior art network integration systems do not permit advertising to be linked with the status of the home automation network.
      While some of the prior art may teach some solutions to several of these problems, the core issue of integrating disparate home automation networks with Internet based communication control systems has not been solved by the prior art.

Objectives of the Invention

Accordingly, the objectives of the present invention are (among others) to circumvent the deficiencies in the prior art and affect the following objectives in the context of a Smart Gateway Power Controller (SGPC):

    • (1) Provide for a network integration system and method that permits formation of home automation networks with a set of subnets.
    • (2) Provide for a network integration system and method that permits multiple ways to interact with a home automation network.
    • (3) Provide for a network integration system and method that permits users to interact with any home automation device by connecting thru a SGPC device.
    • (4) Provide for a network integration system and method that permits a method to provide web banners integrated with the interaction with home automation devices.
    • (5) Provide for a network integration system and method that permits a mechanism to see the network view of the home automation devices.

While these objectives should not be understood to limit the teachings of the present invention, in general these objectives are achieved in part or in whole by the disclosed invention that is discussed in the following sections. One skilled in the art will no doubt be able to select aspects of the present invention as disclosed to affect any combination of the objectives described above.

BRIEF SUMMARY OF THE INVENTION System Overview (0100)

The present invention in various embodiments addresses one or more of the above objectives in the following manner. The present invention as generally depicted in FIG. 1 (0100) implements a Smart Gateway Power Controller (SGPC) (0110) that acts as a bridge between a power source (0101) and associated power source cabling (0102) and power load cabling (0103) to supply power to one or more electrical loads (0104). The SGPC (0110) incorporates a power switch (0111) and power/energy meter (0112) that are interfaced to a microcontroller unit (MCU) (0113) or other computing device operating under control of software read from a computer readable medium (0114). The MCU (0113) interfaces with one or more wireless network interface modules (0115, 0116) which communicate to one or more computer networks that may include the WiFi-based Internet, local computer networks, and/or other networks such as ZIGBEE®, etc.

System Application Context (0200)

A typical application context for the present invention is generally illustrated in FIG. 2 (0200), wherein a user (0201) interfaces with a graphical user interface (GUI) (0210) that may be embodied on any number of devices including but not limited to a mobile phone (0211), laptop/desktop computer (0212), and/or tablet computer (0213). This GUI typically operates under control of software read from a computer readable medium (0202) that incorporates network protocols that communicate over a computer network (0203) (such as the Internet) directly to the SGPC devices (in this case SGPCs are APs) or indirectly to the SGPC devices via a local wireless router (0204). This wireless router (0204) then communicates with one or more SGPC devices (0221, 0222, 0223) to control power switching to any number of load devices (0231, 0232, 0233, 0234) using any number of SGPC associated power receptacles. In the direct communication with a SGPC, the SGPC acts as an AP to consumer devices and at the same time may act as a client to a home gateway (0204). In the case of indirect communication, the SGPC is a client to the home gateway (while also acting as an AP to other devices). The dual roles are illustrated in FIG. 3 (0300). FIG. 4 (0400)-FIG. 7 (0700) illustrate the direct and indirect communications between consumer devices and SGPCs. As generally illustrated in these figures, the SGPC may be configured to directly communicate with other SGPCs in a HAN, and/or be configured to indirectly communicate via a home gateway router (0204). As generally illustrated in FIG. 4 (0400), consumer devices can directly communicate with SGPCs without going through a home gateway. In this instance, the SGPC is an AP to the consumer device and simultaneously a client to a home gateway.

Method Overview

The present invention system may be utilized in the context of an overall network integration method, wherein the network integration system described previously is controlled by a method having the following steps:

    • (1) Searching for an AP to connect/reconnect. After SGPC power up, searching and connecting to an AP based on a connection rule, with options to connect to other Aps if the network configuration changes (self-adaptivity)).
    • (2) Exchanging network configuration messages between SGPCs and/or external network devices (network maintenance messages).
    • (3) Exchanging runtime (maintenance) HA messages between SGPCs and/or external network devices (home automation functionality messages).
    • (4) Proceeding to step (1).

Integration of this and other preferred exemplary embodiment methods in conjunction with a variety of preferred exemplary embodiment systems described herein is anticipated by the overall scope of the present invention.

Network Integration Overview

The present invention extends the functionality of SGPCs as detailed herein to incorporate extended network interactions and tighter integration of network functionality, home control functionality, and communication across and within the home gateway network interface. To this end, the present invention is generally focused on the inter-networking of multiple home automation devices (SGPCs being one example) and the interactions of HA devices as a group with users (a man-machine “social network”) where information is pushed and pulled just as within a conventional social network. While the discussion herein is with respect to networks comprising SGPCs, the present invention is not necessarily limited to this particular type of network interface or communication methodology.

Within this overall network architecture, the issues that the present invention generally addresses include:

    • How multiple HA devices in a home form a network so that they can work in a coordinated/concerted way;
    • How the interactions with the users are affected when HA devices are formed as network;
    • How the content (setup, action, and monitoring of home devices) of the web server hosted at a HA device is delivered and presented to consumers; and
    • How other opportunities, such as customized advertisement and web banners, are integrated in the man-machine interactions.

In the following discussion SGPCs are used to represent home automation devices to make the description more concrete. But the present invention scope applies to all WiFi base automation devices and non-WiFi based automation devices within a home automation networking context.

Smart Gateway Power Controller (SGPC) System Overview

The Smart Gateway Power Controller (SGPC) forms the basis of much of the functionality in the present invention and addresses the deficiencies associated with the prior art home automation systems. FIG. 1 (0100) generally illustrates the functional blocks of a typical SGPC, with one or more functional blocks being physically implemented as one component. It generally comprises a small form-factor device directly plugged into a power outlet. It contains one or more power sockets, into which consumers plug in power suppliers to their home appliances. One or more independent relay switches controlled by the MCU are connected to the socket(s). The switch(s) can be turned on and off by the MCU. A typical SGPC can measure the energy consumption of the plugged in appliances in terms of instant power consumption (watt), energy consumption (watt-hour), voltage and current. A typical SGPC is a cost-effective 3-in-1 home automation device: network gateway+load control switch+energy measurement. The small form factor of this device has the size of a regular power adaptor. On the networking side, it comprises two-way communication with the Internet and two-way DIRECT communication with a WiFi devices (PC, laptop, smartphone) at home.

A SGPC may optionally contain an alternative wireless module to communicate with an existing home automation device, to provide the latter the capability to be accessed from Internet. An existing automation device can be a ZIGBEE® or Z-WAVE® based device.

FIG. 2 (0200) generally illustrates the usage of the SGPC device. The following describes a typical use case scenario:

    • User opens a web page of a SGPC from anywhere at home or outside with her smartphone by typing a URL address along with some security information (e.g., password, etc).
    • The web page shows switch status, energy consumption of the connected consumer device(s) at home.
    • User clicks a button to turn on or off a switch instantly or choose a schedule—time based or event based—to turn on or off the switch at a later point.
    • User then registers his email address in the web page for the SGPC to forward any events or message to their email account (e.g., switch status change, energy consumption above a threshold, etc.).
    • User also downloads a (platform independent) software program or data to their smartphone that would provide additional functionality, for example, to view a histogram of her energy consumption in a more detailed fashion on their smartphone.
      This system can be better described in terms of the networking architecture, functionality provided by the SGPC, and interaction between users and a typical SGPC configuration. This information is provided in more detail below.

Networking Architecture Network Structure Subnet and Sub-Gateway (0300, 0400, 0500, 0600, 0700)

A SGPC works with home residential gateway as a client (station), and use the residential gateway to communicate with the Internet cloud. On the other side, it serves as a secondary or sub-gateway to a subnet that consists of a set of WiFi based client devices it has control over, as well as any consumer devices that can communicate with it. If the SGPC has the wireless interface to communicate with ZIGBEE® devices, it can also control and read data from the latter. FIG. 3 (0300) illustrates the two roles a SGPC plays.

In other words, SGPC is a sub-gateway that “separates” the home automation network from the existing home network, while having the two networks communicating with each other. The home automation network has different subnet address than that of the home network. FIG. 4 (0400) illustrates a typical configuration setup.

A SGPC can communicate with WiFi and ZIGBEE® based sensors, and the sensor data can be used to schedule turning on and off the switch, as well as reported to consumers. It can communicate with any devices (WiFi based, ZIGBEE® based, another SGPC) devices to coordinate the control actions.

FIG. 5 (0500) and FIG. 6 (0600) illustrate examples of multiple SGPC devices with different network topologies. These SGPC have their own subnet and can talk to each other as in an IP mesh network.

FIG. 7 (0700) shows a case where SGPC can communicate with ZIGBEE® network. As an example of multiple SGPC communicating with each other, when a TV is turned on with one SGPC, the light controlled by another SGPC may be turned off.

Another example is that when a ZIGBEE® based temperature sensor reads a data above a threshold (set by consumer on the SGPC), the SGPC connected to an air conditioner turns on. The advantage of separating the switch and sensors, as opposed to the thermostat where the switch and sensor are in the same location, is that users can put the sensor anywhere they want the air conditioner to be responsive.

It should be noted that the network architecture described here is different from the WiFi ad-hoc and WiFi-direct mode in that:

    • WiFi ad-hoc is a point-to-point communication while the present invention architecture is point-to-multiple points; and
    • WiFi-direct cannot have its own subnet, and does not have the relay/routing capability mentioned above.
      WiFi-direct is generally a good methodology for point-to-point communication, but not for a server-client situation.

Preferred Exemplary SGPC Architecture (0800)-(1600)

A preferred exemplary system electrical block diagram of a typical SGPC system is generally illustrated in FIG. 8 (0800)-FIG. 9 (0900), with exemplary detail of these system blocks depicted in FIG. 10 (1000)-FIG. 16 (1600). This preferred embodiment comprises the following circuits:

    • Line Power Interface (0901)—As detailed in FIG. 10 (1000), the input outlet brings 110V AC in through the fuse and split into two paths. The first path converts the AC voltage to a DC voltage by 4-diode bridge rectifier. A transformer steps down the voltage to the level for further regulation. DC regulator (U3) provides +5 VDC supply for the remaining circuits of the unit. The second path brings 110V AC voltage forward to the output socket via a power relay in the power switch (0905) as detailed in FIG. 15 (1500).
    • Voltage Regulator (0902)—As detailed in FIG. 11 (1100), the DC Regulator brings +5 VDC from the line power interface (0901) further down to +3.3 VDC for supplying a wireless transceiver in the wireless communications interface (0903).
    • Wireless Communications Interface (0903). As detailed in FIG. 12 (1200), a wireless transceiver receives the commands from the computer or/and other WiFi or wireless device. The received command via the wireless receiver interface (not shown) will provide a logic signal (SWITCH) to turn on/off the transistor switch (Q1). Q1 controls the on/off position of the power relay in the power switch circuitry (0905) based on commands from the PMCU and may optimally be implemented using bipolar or MOS fabrication technologies. Some preferred embodiments of the present invention may use a GainSpan WiFi module that contains a WiFi SOC chip (this SOC chip contains the baseband and wireless transceiver and an integrated microcontroller unit).
    • ZIGBEE® Wireless Interface (0905). As generalized in FIG. 8 (0800) and detailed in FIG. 13 (1300) and FIG. 14 (1400), the SGPC (0810) may incorporate a ZIGBEE® interface (0814) in the overall SGPC design to permit heterogeneous wireless networks using SGPCs to communicate with a wide variety of existing home automation wireless networks. While a wide variety of embodiments of this wireless interface are anticipated, a preferred embodiment incorporates the use of a Texas Instruments model CC2531 ZIGBEE® communications controller as generally illustrated by the block diagram of FIG. 13 (1300) and exemplary implementation schematic of FIG. 14 (1400).
    • Power Switch (0905)—As detailed in FIG. 15 (1500), a power relay is a gate between the line power interface power input and the output power outlet and is controlled by the transistor switch in the wireless communications interface (0903). The power relay is protected from the over current surge by a Zener diode.
    • Energy Measurement (0906)—As detailed in FIG. 16 (1600), an integrated circuit (IC) (1601) is incorporated for measuring energy consumption. One skilled in the art will recognize that many forms of energy measurement circuits may be deployed to achieve this functionality.
      One skilled in the art will recognize that these functional blocks may be implemented in a wide variety of ways well known to those skilled in the art of circuit design and as such are only exemplary of the techniques taught by the present invention.

Summary of SGPC Functionality (1700)

A summary of SGPC functionality will now be presented. As illustrated in FIG. 17 (1700), the SGPC may be generally described in terms of several functional blocks. The SGPC (1710) is generally a small form-factor device that is directly plugged into a power outlet (1701). It contains one or more power sockets, into which consumers plug in power cords connected to their home appliances or consumer devices (1702). One or more independent relay switches (1711) controlled by a MCU (1712) are connected to the socket(s). The switch(s) (1711) can be turned on and off by the MCU (1712). The SGPC can measure the energy consumption (1713) of the plugged in appliances in terms of instant power consumption (watt), energy consumption (kilo-watt-hour), voltage and current.

A SGPC contains a WiFi module (1714), and may communicate with the Internet via a (home) gateway and communicate directly with a WiFi devices (PC, laptop, smartphone) at within the localized HA environment. A SGPC can optionally contain an alternative wireless module (1715) to communicate with an existing home automation device, to provide the latter the capability to be accessed from Internet. An existing automation device can be a ZIGBEE® or Z-WAVE® based device.

Consumers may connect their Internet devices directly via WiFi interface with a SGPC or from the Internet, and open a web page hosted on the SGPC and monitor the power consumption of the plugged in appliance(s) and control the switch(s) that turn on/off the appliance(s).

A SGPC is a particular type of home automation device. However, it should be stressed that the teachings of the present invention apply to any home automation (HA) device based on IP that supports a web server interface. Within the following discussion the terms SGPC will be used interchangeably with “HA devices.”

Preferred Method Structural Overview (2400)

While the present invention may be implemented in a variety of methods, some preferred methods are generally illustrated by the flowchart structure detailed in FIG. 24 (2400). This general overview diagram details the relationships between major functional blocks of the network interaction management methods (2410) and the web banner content delivery methods (2420) that are discussed in more detail below.

Inter-HA Device Networking

When multiple SGPCs are deployed at home, they may work as independent devices or work as a group in a coordinated way. A SGPC may have its own subnet as an AP while joining another network as a client. This “double role” has been mentioned earlier and discussed in the Provisional Patent Application for POWER CONTROL SYSTEM AND METHOD referenced above. In addition, a SGPC may contain a gateway into a non-WiFi network, such as ZIGBEE® network. FIG. 18 (1800) generally illustrates the “multiple roles” a SGPC can play. In FIG. 18 (1800), SGPC2 is a station/client to SGPC1 in SGPC1's subnet and SGPC2 has its own subnet. A given SGPC contains a router that routes information between subnets.

When multiple SGPCs are connected including their non-WiFI subnets, a heterogeneous network is formed, where WiFi based SGPCs connect with each other, and with other types of networks, such as ZIGBEE® subnet, via a network gateway, etc. From a user's standpoint, the communication between these devices (WiFi, ZIGBEE®, BLUETOOTH®) is transparent, and all these devices are created equal—they can do something and may work together to achieve this goal. What is taught by the present invention herein is the networking between SGPCs and their associated non-WiFi subnets. The organization and presentation of the information on how they are connected for management and diagnostic purposes is discussed later.

As generally illustrated by the flowchart of FIG. 25 (2500), the overall flow in managing HA home network can be described in the following steps:

    • Forming a network (2501);
    • Exchanging networking configuration and device capability (2502); and
    • Exchanging home automation related information (2503).
    • Repeating these steps in sequence.

Forming a Network of HA devices

The multiple SGPCs will form a tree like network, or a mesh network. A variety of network configuration scenarios are anticipated in conjunction with the present invention, including but not limited to the specific scenarios detailed below.

Scenario 1 (Initial Self-Formed Network)

Consumers deploy one SGPC after another. These SGPCs will form a tree like structure as generally illustrated in the user interface (UI) in FIG. 22 (2200). The tree root is the first deployed SGPC. For any node (acting as an AP), its clients form its children nodes. Once a SGPC is powered up, it scans the frequency space, looking for any APs (early-deployed SGPCs or home gateway). It chooses an AP based on pre-defined rules, such as the signal strength of the AP, or the SSID, or the capability of the SGPC. The choices will be based on a rule or the combination of rules.

Signal Strength Rule

The signal strength rule is easily understand as it involves selecting an AP based on the highest available SGPC wireless signal strength, and will not be discussed here.

SSID Rule

All SGPCs will have SSID in certain pattern, for example, “CompanyID—xxx”. By searching the pattern, a SGPC will be able to detect other SGPCs as candidates to connect. Note that a SGPC can choose not to join any existing SGPC subnet, and instead just join the primary home network if the “joining” rule dictates this behavior.

Capability Rule

SGPCs broadcast their capabilities to each other—to be discussed later. A SGPC may be configured to connect to SGPCs with certain capabilities.

AP Search and Connection Method (2600)

A generalized search and connection method useful in some preferred invention embodiments to form the tree like network structure described above is generally illustrated in FIG. 26 (2600).

Scenario 2 (Adaptive Network)

Once all deployed SGPCs form a network as in scenario 1, the inter-connection between SGPCs can be adjusted/reconfigured when consumers start to configure SGPCs for controlling and monitoring home devices, or certain events happen, such as a SGPC is not responsive.

Case 1

The currently connected SGPC is no longer responding or the response is slow, meaning the SGPC may be broken, busy or the traffic to/from is too heavy, therefore a new AP needs to be found.

Case 2

Assume SGPC1 in FIG. 18 (1800) controls a TV, and SGPC2 controls a light. Consumer can configure SGPC1 and SGPC2 based on this simple rule:

    • If SGPC1 is switch on (TV is on), then SGPC2 is turned off if it is on.
      In this case, if SGPC1 and SGPC2 are not already in the same subnet, they would be put into the same subnet to improve the performance.
      Case 3

Assume SGPC2 controls an air conditioner, the ZIGBEE® network associated with SGPC1 contains a ZIGBEE® sensor measures the room temperature (see FIG. 18 (1800)). Suppose the consumer configures the SGPC2 such that its control action depends on the measurement of the sensor. If SGPC1 and SGPC2 are not already in the same subnet, they are put into the same subnet.

Rule definitions that associate a control action with measurements or data from another device are discussed in the Provisional Application for POWER CONTROL SYSTEM AND METHOD referenced above. As the network is reconnected, the UI as generally illustrated in FIG. 22 (2200) will typically reflect the network changes in real-time.

AP Reconnection Method (2700)

A generalized AP reconnection method useful in some preferred invention embodiments to reconfigure the network structure described above is generally illustrated in FIG. 27 (2700).

Scenario 3 (Manually-Formed Network)

Consumers can manually reconfigure who connects who for an established network. This is done simply by reconnecting the nodes in a tree, as illustrated in FIG. 23 (2300), where node “Meg's computer” is now connected to “Basement TV” after disconnected from “Dryer” (compare with FIG. 22 (2200)). Here the names are “nicknames” assigned to a node to help identify/remember the functionality of a HA device.

The scan and discovery of a HA device to connect to is part of a wireless device PHY/MAC layer capability and not detailed herein, as this functionality is application specific to the wireless interface used and well within the implementation capability and discretion of one of ordinary skill in the art. The network connection information—the tree structure—is optimally presented in XML format. The information is broadcast among the SGPCs and is used by UI.

Every SGPC broadcasts its own node information to the network at initialization and every time a reconnection is done, as shown below. The node information includes node name, type, description, and the AP (parent) connected and clients (children). A typical format for this is provided below:

<node>  <name> CompanyID100-001 </name>  <type> WiFi <\type>  <nickname> Basement TV <\nickname>  <description> Samsung LED TV </description>  <parent> Home Gateway (192.168.1.1) </parent>  <child> CompanyID100-002 </child>  <child> CompanyID100-005 </child> <\node>

Each SGPC may store the information on all the nodes it received as in the following example:

<netConfigure>  <node>   <name> CompanyID100-001 </name>   <type> WiFi <\type>   <nickname> Basement TV <\nickname>   <description> Samsung LED TV </description>   <parent> Home Gateway (192.168.1.1) </parent>   <child> CompanyID100-002 </child>   <child> CompanyID100-005 </child>  <\node>  <node>   <name> CompanyID100-002 </name>   <type> WiFi <\type>   <nickname> Air conditioner <\nickname>   <description> A/C in bedroom </description>   <parent> CompanyID100-001 </parent>   <child> XYZ-004-01 </child>  <\node>  <node>   <name> CompanyID100-005 </name>   <type> WiFi <\type>   <nickname> Light <\nickname>   <description> Bedroom light </description>   <parent> CompanyID100-001 </parent> </node> <node>   <name> XYZ-004-01 </name>   <type> ZIGBEE <\type>   <nickname> Basement TV <\nickname>   <description> Temp sensor </ description>   <parent> CompanyID100-001 </parent>  <node> </netConfig>

Reference FIG. 22 (2200) for an example of tree like network connection.

Information Exchange Between SGPCs

Once the SGPCs and non-WiFi device are networked, they can exchange information. There are two preferred types of SGPCs and non-WiFi HA devices: actuators and sensors. Actuators are devices that can exert actions, such as switching and regulating. Sensors are devices that measure physical and chemical variables, such as temperature, pressure, and electricity. Actuators can take actions based on measurements of any sensors.

SGPCs can combine both actuators and sensors in one unit. But the communication between them is generally considered an internal SGPC function and in most case not involved with inter-networking capabilities between HA devices.

It is important for the HA devices (WiFi based and non-WiFi based) to exchange a set of messages in order to work together. The purpose of exchanging information is twofold:

    • It is important for actuators to know the data/measurement from another device, if the action of one actuator depends on the data/measurement of another; and
    • As discussed later, consumers can see the information on all devices when they are connected with one of the devices.

Initial Capability Information Exchange (ICI)

When HA devices first form a network, they exchange certain information on their capabilities. This information is broadcast among the HA devices. The capability information may include, but not limited to the following:

Type of HA Device

HA device types may typically include but are not limited to actuators, sensor, or combo (with both actuator and sensor).

Sub-Type of HA Device

For an actuator, the sub-types may include:

    • what sub-type it is—a switch or regulation on what variables (e.g., electricity, water, etc.);
    • what sensor data its control action is based on.

For sensors, the sub-types may include:

    • what sub-type it is in terms of what measurements it collects—temperature, pressure, etc.

The present invention anticipates a standardized set of HA types and sub-types as detailed in the following exemplary table that lists a subset of this standardized type/sub-type sets.

Control variable/ Dependency data to other Type Subtype available device Description actuator Switch On/off Actuator status and Sensor data (same for below types) Regulator Reference/ Regulator control keeps a value, value (e.g., lower and temperature) upper limit at a certain reference point, with lower and up point, beyond which alert events will be generated Motor On/off, Window Speed opener, door opener Alarm/ On/off buzzer Sensor Temperature Temperature Electricity Watt, kilo- meter watt-hour Water meter ACM/h (actual cubic meters per hour) Gas meter Liters per second Camera Video Motion Movement sensor detected Air quality Dust detector percentage

This capability information is exchanged once during the device's runtime—defined as the time between it is powered up and the time is powered down or goes into a bad state. This information is general termed initial capability information (ICI) exchange. Once a HA device gets the ICI from another HA device, it knows what information it can get from that HA device.

The ICI may be presented in XML as detailed below:

<intialMesg>  <name> CompanyID100-001 </name>  <type> actuator </type>  <subtype> switch </subtype>  <description> any text here </description> </initialMesg> <initialMesg>  <name> xyz100-001 </name>  <type> sensor </type>  <subtype> temperature </subtype>  <description> any text here </description> </initialMesg>

The name part of the message is the name of the node. The name is used for cross reference between the network view and functional view (the two views will be discussed in details below).

Runtime Information (RI) Exchange

During the run time, HA devices may exchange the following information:

    • Requests to subscribe status, events and measurements (one time, periodic, events);
    • For actuators, status of a switch and regulator in response to requests;
    • For sensors, the measurements of a sensor over a period of time in response to requests;
    • The pending action scheduled of actuators; and
    • Events happened on actuators and sensors.
      The RI exchange can be one time, periodic with a given a period, and event-driven. FIG. 28 (2800) illustrates an exemplary flowchart depicting how runtime information (RI) is exchanged among various SGPC devices.
      RI Implementation

An exemplary RI implementation may include the following:

    • The information is carried in XML format. The following are samples of the XML messages.
    • Adaptive traffic rate control. When to send RI can be controlled based on the current traffic. If the traffic is busy, the “scheduled” RI exchange can be delayed a little to a time when the traffic is light.

EXAMPLES

The following example illustrates the RI functionality as depicted in XML format for a situation in which Node “CompanyID100-003” subscribes from Node “CompanyID100-001”:

 <runtimeMesg>   <type> Subscribe </type>   <from> CompanyID100-001 </from>   <dataType> switchStatus </dataType>   <!-other available data types:   sensorData, regulatorStatus, connectionChange -->   <frequency> onetime <\frequency>  </runtimeMesg> Node “CompanyID100-001” responds to Node CompanyID100-003:  <runtimeMesg>   <type> response </type>   <to> CompanyID100-003 </to>   <dataType> switchStatus </dataType>   <data>open <\data>  </runtimeMesg> More examples of responses:  <runtimeMesg>   <type> response </type>   <to> CompanyID100-001 </to>   <dataType> sensorData </dataType>   <data> 98 <\data>   <dataUnit> C-degree <\dataUnit>  </runtimeMesg>  <runtimeMesg>   <type> response </type>   <to> all </to>   <dataType> connectionChange </dataType>   <parent> CompanyID100-002 </parent>   <child> CompanyID100-002 </child>   <child> CompanyID100-005 </child>  </runtimeMesg>  <runtimeMesg>   <type> response </type>   <to> CompanyID100-003 </to>   <dataType> regulatorStatus </dataType>   <regulateVariable> temperature </regulateVariable>   <referenceValue> 75 <\referenceValue>   <referenceValueUnit> C-degree<\referenceValueUnit> </runtimeMesg>

Consumer-SGPC Interactions

Consumers interact with the home automation system—the network of HA devices (SGPCs and their companion devices)—in various modes. While the present invention anticipates a variety of consumer/SGPC interaction modes may be supported in any particular embodiment, the following four modes are specifically anticipated as being optimal in many preferred embodiments:

Mode 1: Web Page Hosted on a SGPC

Consumers directly interact with the web server hosted on a SGPC. There is one unique feature of the web server:

    • Consumers only need to connect to one of the SGPC to get the information of all SGPC on the server.

This feature of connecting to one SGPC and get all the information is supported by the fact that all SGPCs exchange information on a regular basis or on-demand.

This feature is in contrast to some existing user interfaces where an application on consumers' device must communicate with every HA device to get its information. Or a proxy server must do so for the consumers so that the consumer device can communicate with the server to get the information.

Within this mode, there are two anticipated methods of implementing this functionality:

Centered Web Page

All the information a consumer wants to know—information on the connected HA device or that of other HA devices—comes from the database of the connected HA device. The connected HA device gather the information form other HA device through the RI exchange discussed before.

Distributed Web Page

When a consumer wants to get the information from another HA device, the connected HA device simple route the request to the target HA device and redirect to the web page on that HA device. The consumer device does not need to reconnect to another device as it is still connected to the first device, just the web page on the second device now is routed through the first device.

Implementation: To use this mode, a consumer's device must have the access information on the SGPC to be connected. This happens in two cases: (1) when the device is in the vicinity of the SGPC using WiFi communication; and (2) when the device is outside home using Internet to get connected. The first case is a standard function of a WiFi device. In the second case, the consumer devices must have the IP aggressing information of the SGPC. How consumer devices obtain the IP addressing information is discussed below.

Internet Proxy Server as a Yellow Book

When the consumer is outside the home, she must use Internet to communicate with the SGPC. If a consumer (or consumer device rather) does not have the access information of the SGPC, it contact a proxy server on the Internet (e.g., www.CompanyID.com). The proxy server serves as a yellow book as it is in a constant “maintenance” mode to communicate with a SPGA to update the SGPA's address information in its database.

The details on how the proxy server gets and keeps the addressing information of SGPCs is detailed in the Provisional Patent Application for POWER CONTROL SYSTEM AND METHOD referenced above.

When the consumer device contacts the proxy server, it logs in to the consumer's account, and the access information of all the SGPCs in her home is right there in the web page of her account. After clicking the address link of a particular SGPA, the consumer device is in direct communication with the SGPA. Example of the link to the addressing info:

    • http://www,CompanyID.net/homeautomation/xyz1023/sgpc—001
      where xyz1023 is the username of the home owner, and sgpc—001 is the name of a particular SGPC. This link directs a user to the web page of a SGPC at home.

The proxy server not only maintains the addressing information of the SGPCs, it also maintains the addressing information of the consumer devices. The mechanism to maintain the addressing information of consumer devices is the same as that for SGPCs. As a result, not only consumer device can get the addressing information of SGPCs and can initiate communication with the latter, the latter can initiate communication with the former as well. The “reverse” initiation is necessary when SGPC wants to push information into consumer devices, to be discussed later.

Mode 2: Proxy Server Hosted Web Server

SGPCs send all the information it would present on their own web pages to a proxy server, which stores the information in its database, and presents the web pages on its own web server. This mode is commonly used today for interaction between consumers and home devices. The advantage of this mode is that a web server is not needed as a yellow book. The disadvantage is that consumers do not trust a third party where their information is stored.

Mode 3: Application Based

Consumer can download an application to her device, an iPhone® or other mobile device for example. The application does one or all of the following:

    • Background Proxy Server. It has a small proxy server running in the background, which does the same as the Internet proxy server described before—in a regular interaction with the home SGPCs and updates the SGPC access information in its database. With this background proxy server, consumers need no intermediate Internet servers to provide addressing information, in contrast to the requirements currently imposed by the prior art. This device based proxy server is different from an Internet proxy server in that it is only interested in owner's home SGPAs, while the Internet proxy server maintains addressing information for many homes' HA devices. This functionality may be implemented as follows. If the consumer devices are powered off, than the proxy server will lose connection with SGPCs. In the case, when the consumer device is powered up again, the proxy server must first contact the Internet proxy server to “bootstrap”—get the updated SGPC addressing information (its old addressing information may be stale). So the Internet proxy server is not dispensable. But after the bootstrap, the small proxy server will maintain the IP addressing information by regularly communicating with the home devices the same way an Internet proxy server does.
    • Constant Proxy Server Updates. It communicates with the Internet proxy server constantly to update its own addressing Information just like a SGPC does (see Mode 1). As a result, when a SGPC wants to notify a consumer of an event (see the Mode 4: Push information to consumer), it contacts the internet proxy server and gets the addressing information of the consumer device.
    • SGPC Interaction. It interacts with the SGPCs and gathers the information and present in a user interface running on the consumer device. The UI can be customized to fit the owner's taste. This application can talk to one SGPC or multiple SGPC at the same time.
      Mode 4: Push Information to Consumer

When a consumer device registers itself to a SGPC to receive push information or notification, their device can receive status change, events, or measurement in their email or text messages. While a consumer can register on more than one SGPC, it is not necessary since one SGPC can get the data from other SGPC for the consumer.

In addition to the email and text messages, the SGPC can find the addressing information of a smartphone from the Internet proxy server. When the consumer turns on the application on the iPhone®, tablet, or other mobile device, the SGPC detects that the registered device is on, and starts to stream data to the consumer device. The application on the consumer devices may pop up windows displaying these events.

The reason the SGPC knows an IPhone® is on is that the small device based proxy server mentioned in Mode 3 regularly communicates with the SGPC when it is on.

With these four modes, consumer devices and home HA network form a type of man-machine “social” network. They are constantly in touch with each other, sending and pushing information to each other.

Home Based Web Server Content

A SGPC contains a web server for a home, and can be personalized in terms of the house location, the house income, the energy usage and controlled house electronics device. The web server is unique in the sense that it is dedicated to a home and is different from an Internet hosted server where the information has to be uploaded and the web pages dedicated to a consumer share the same server with others. Besides the security and privacy issue of the Internet hosting server, it is difficult for a third party to target services to a consumer or their home. The present invention allows the “home” web page to be personalized with supplementary information on the web server. Within this context the home based web server acts as a “smart digital TV” at home, where targeted information can be delivered.

The user interface, either the web page hosted on SGPC or the UI running on consumer devices, is primarily responsible for presenting the home automation information and allows consumers to control and configure HA devices and monitor the measurements.

In addition to the home automation information, the present invention may provide the following supplemental content:

Web Banner

Web banners may be provided by web servers hosted on SGPCs and/or Internet proxy server. Web banners are anticipated to be added to web pages and streamed to consumers in at least two cases.

Scenario 1 (Waiting for Connection)

There are pauses when consumers try to connect to a SGPC via a proxy server. The pauses provide a short window to put out the web banner on screen.

Internet proxy server or device based proxy server monitors the latency from the moment a consumer click a SGPC to get connected to the moment the connection is established and the SGPC web page shows up. During this “waiting” window, SGPC puts on web banner with the content described below.

When the web page from the connected SGPC shows up, there are two typical cases configurable by consumers or proxy server manager. One case is that web banner stops when the SGPC web page shows up. The other case is that the banner will continue, blending into the new web page in the normal interaction between the consumers and the SGPC (see below).

Scenario 2 (Interaction with SGPCs)

When consumer interacts with a SFPC in one of the 4 modes discussed above, web banner can come as a continuation of that during the connection “pause”, or as independent one.

Web Banner Content Delivery Method (2900)

A generalized web banner content delivery method useful in some preferred invention embodiments that depicts the overall web banner content delivery process, taking into consideration of the two scenarios discussed above is generally illustrated in FIG. 29 (2900).

Content Delivery Mechanism (1900, 2000, 2100)

Web banner content on the SGPC web server is either come from local storage or from real-time “streaming” from an Internet server. An Internet web server dedicated to serving home based web content (usually the same server as the proxy server), will stream content targeted to each home, much in the same way as Internet TV or video-on-demand streamed into home. The difference is that the content is to be displayed in the banner of the web page hosted in the always-on SGPC or HA devices.

The web server, herein termed a home-bound content (HBC) server, typically comprises the following:

    • A backend database with information on the profile of each home and the associated content to send to each individual home
    • A scheduler that manages the content to be delivered to homes by updating the database
    • A front-end interface that “detects” if the web pages of a SGPC are alive (meaning the SGPC device is connected with a consumer device and the web page opened) or otherwise—idle. The front-end communicates with the software on the SGPC to detect this.
    • A delivery server that interacts with the database and the frontend, and deliver the content
      The HBC server typically sends/streams banner content, including data and video clips to a SGPC, in the following cases:
    • When the SGPC request the content. The SPGC software may send a request for web banner content along with what type of content to get, depending on the current interaction context with the users (see the discussion below).
    • When the web pages on the SGPC is alive, push the content to SGPC (unsolicited).
    • At a given time when the traffic is slow, for example, during mid-night, regardless whether the SGPC is alive or a content request is received.
      In the first two cases listed above, the content is displayed real-time on the web banner whereas in the third case the content is stored in the local storage of the SGPC for later use.

FIG. 19 (1900) generally depicts a HBC server connected with a SGPC. FIG. 20 (2000) generally illustrates how the content is pushed to SGPC and FIG. 21 (2100) illustrates how content is pulled from SGPC.

Web Banner Content Delivery Methods (3000,3100,3200)

A generalized web banner content delivery method for the Scenario 1 (delivery into the pause window during the connection) useful in some preferred invention embodiments is generally illustrated in FIG. 30 (3000).

The flowcharts depicted in FIG. 31 (3100) and FIG. 32 (3200) illustrate the processes of the content delivery during the normal operation of SGPC. The flowchart of FIG. 31 (3100) illustrates the process of content delivery on the HBC server side, and the flowchart of FIG. 32 (3200) illustrates the process of the content delivery on the SGPC side.

It should be noted that a SGPC typically sends content requests to HBC server with the context of the interactions with consumers. The context of the interaction may include:

    • the device involved;
    • the action taken;
    • the data read;
    • the location of the device; and
    • other related information.
      Based on the information, the HBC server can select content targeting the context. One way to implement it is for the scheduler of the HBC server and SGPC software to define types of context and the content types/genres, and associate context types with content types in the database, and select content in real time according to the context type. Application examples of this content targeting are detailed below.
      Content

The web banner may include the following supplementary information:

Close-Loop Advertising

The definition of close-loop advertising is that the advertising is related to the location of the SGPC and context of the interaction with home automation functionality (the information relates directly to the device being currently monitored and controlled). Web links are embedded in the web banners for purchasing or more information.

Examples of this may include:

    • When the consumer looks at the status and energy consumption of a light, information about energy-saving light bulbs can appear in the banner enabling the consumer to instantly have comparison with the current light bulbs in use;
    • When the web page shows a significant usage of certain electronic devices, certain advertisement from local utility companies and stores on similar devices and services with energy-saving features can be posted.
      Local Commercials and News

Like what is shown on some TV channels, this gives general purpose local commercial advertisements and news. The advertisements and news are local and targeted to a well-defined community/house hold. For example, Base on the time of day, food advertisement from local stores can be posted.

Instant Energy Usage Analysis and Energy Saving Suggestions

From time to time, suggestions and web links on how to save energy appear on the web banner. Examples of this may include:

    • When too many lights are on or too many TVs are on, a friendly reminder will pop up in the banner to turn off some lights;
    • The total home energy and histograms of some devices will roll over the banner

User Interface

When a consumer device is connected with a SGPC, a web page can be opened on the SGPC. Consumers may either control and monitor that SGPC and/or control and monitor other SGPCs via the connected SGPC. The present invention anticipates at least two views of the user interface in this context.

Functional Views

Provisional Patent Application for POWER CONTROL SYSTEM AND METHOD as incorporated herein has discussed the functional view. This view is for users to perform home automation configuration and monitor home automation device status. This functionality is summarized here without further detail. The functional view contains the following information:

    • For actuators, the view allows users to check the status of actuator, schedule and configure actions of actuators. The control action can be scheduled one time only or periodic.
    • For sensors, the view displays the sensor measurement such as energy consumption. The measurement can take the format of tabular display, or histogram, and can be zoomed in and out.
      Additionally, the viewer allows users to associate an actuator action with another other actuator status and sensor data, and register for event notifications to be sent to their email or smartphones, and download applications.
      Network View

This view shows the tree structure of home automation network discussed before, as generally illustrated in FIG. 22 (2200). The view includes node connections, node properties—IP address, wireless interface (WiFi, ZIGBEE®, etc.), etc. This is for system diagnostic purposes and for advanced user control. In most cases, consumers are interested in the functional view only.

In this view, all the nodes a SGPC can detect will show along with their connections with each other. The view shows the status of each node—live (connected with user, green color), standby/idle (running but not connected with a user, yellow color), out-of-service (in a bad state, may need service, red color). For example, as generally depicted in FIG. 22 (2200), node “washer” is in active mode, node “Xbox” is idle, and node “Theo's Computer” is currently down.

The network view will automatically refresh periodically to reflect the updated network connections. Users can press the “Refresh” button to manually fresh it.

When a user clicked a node in the view, a window pops up with more information on the node, as generally illustrated in FIG. 22 (2200).

A user may manage the network in any one of the following ways:

    • Reconnect one node to another by simply “draw” a line between the 2 desired nodes. For example, in FIG. 23 (2300), node “Meg's computer” is now connected to “Basement TV” after disconnected from “Dryer” (compare with the configuration of FIG. 22 (2200)).
    • Restart a node by clicking the restart button (see the pop-up window depicted in FIG. 22 (2200)).
    • Configure the properties of node (see the pop-up window depicted in FIG. 22 (2200)).
